2.A.114.1.5
CstA of 703 aas and 18 putative TMSs. In C. jejuni, this protein plays a role in starvation responses and peptide uptake.  A ΔcstA mutant has reduced use of di- and tri-peptides when used as nitrogen sources. The mutant also has reduced motility and agglutination and shows decreased host-pathogen relationships (Rasmussen et al. 2013).

Species:Campylobacter jejuni subsp. jejuni serotype O:2 (strain NCTC 11168) [192222]
